Asymmetric molecular interactions can preserve the secret of living substances
Non-reinteracting networks can induce the stability of biological systems and allow different states of activity to be adopted. Credit: MPI-DS Asymmetric interactions between molecules may function as stabilizing factors in biological systems. A new model by researchers from the Department of Biomaterial Physics at Max Planck Dynamics and Self-Organizing Institute (MPI-DS) reveals the role of non-regenerative regulation. Scientists aim to…

Color-changing fluorescent dyes allow for accurate temperature measurements within living cells
A novel single fluorophore ratiometric fluorotherm developed using solvent-dyed dyes achieved record sensitivity and enabled live cells and environmental sensing. Credit: Science Tokyo Temperature is an important variable that affects countless biological processes at the cellular level. However, accurate measurement of temperature within living cells remains difficult. Traditional temperature measurement techniques often lack the spatial resolution required to detect subtle…

New biometric material for regenerative medicine: Scientists develop living hydrogel with cell nanocon positive
A new biological material developed by an engineer in Pennsylvania imitates an extracellular matrix, an important component of human tissue. The extracellular matrix acts like a scaffold so that the cells can be cured after damage. Credit: SHEIKHI RESEARCH GROUP/PENN State. Unauthorized reproduction is prohibited. According to Pennsylvania researchers, biological materials that can imitate specific actions in biological tissues may…

World’s first research reveals the mystery of marsupial moles living in the desert
Credit: Photo Mike Gillum, from Science Advances (2025). DOI: 10.1126/sciadv.ado4140 Hidden beneath the dunes, a mysterious creature is gliding across the sand. This isn’t one of the giant worms of Arrakis from Frank Herbert’s science fiction epic Dune. Rather, it’s a marsupial mole, a mysterious small mammal found only in the Australian desert. There are two closely related species of…

What is the cost of living crisis? Luxury travel is booming, with further growth expected
Credit: Unsplash/CC0 Public Domain About 10 years ago, while working at the Badrutts Palace Hotel in the Swiss town of St. Moritz, he was shocked to learn that a customer had requested that an elephant be brought in to deliver a birthday present to his wife. And the hotel made it happen and pushed the elephant into the lobby. This…

Scientists uncover insights into neuron function by measuring two key signals simultaneously in living animals
When triggered by odor, C. elegans olfactory neurons undergo rapid changes in membrane potential and intracellular calcium ion levels, leading to fluctuations in the fluorescence intensity of membrane potential sensors and calcium ion sensors. Researchers at Kyushu University measured these changes simultaneously using high-speed capture under a microscope and subsequent image processing, showing that the two signals encode different information…

Infrared quantum ghost imaging illuminates living plants but doesn’t disturb them
Experimental setup and photon pair correlation. Credit: Optica (2024). DOI: 10.1364/OPTICA.527982 The study, published in the journal Optica, demonstrates live plant imaging of several representative plant samples, including the biofuel crop sorghum. Using a new detector, researchers obtained clear images of living sorghum plants in light much dimmer than starlight. This advancement enables imaging of delicate and light-sensitive samples such…
